Internet Randomly Disconnects

[Tribalstalker]

When trying to play a big MMO game such as World of Warcraft or The Isle after 5 minutes the game disconnects and my computer acts as if the network cable has been unplugged. I have tried using a brand new ethernet cable, different ports in the router, and plugging directly into the modem.  Also when this happens my husbands laptop and our smart tv's continue to work as they are wireless connections.  I can use the internet for streaming shows and other games but the big games cause this issue and than it takes almost 10 minutes for the connection to reastablish itself.
